Let's Make Robots!

Solar Panel

Throw some light on where I can find some solar panels, I am going to use these for powering some smatt components in a robot, and may use the panel for charging the batteries of the same robot ocassionally.

My requirements are

Vout= 5V

Iout = upto 700mA.

NOTE: I am ready to use series/ paralle combinations in the panels and the use DC-DC regulators to meet my requirments.

IMPORTANT: Size And COST matters. I will not be in a position to afford more than $30~$35 for the wholar solar panel part.

Thank You in advance.

 If you use these panels ,45v each you will have to make them up, 12 in series will get you to 5.4v and 2400mA, the cheapest I have seen in a while, check the list of were they ship if you live out side the usa. There are 24 cells in the box so you could make 2 panels or use them for another project.

Go to www.Parallax.com and type in solar panel in the search box.  

I suspect you'll want the 4 pack of 6v panels for $29.   167ma each x 4 in series = 668ma.  other options are available.  generally you want more vout than you need.

I don't know what dimensions you need but a quick check uncovered...
